IMPROVEMENT IN MACHINES FOR BURNISHING THE HEELS 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 145,430, dated December 9, 1873 application iled November 1, 1873.

To all whom it may concern Be it known that I, RICHARD C. LAMBART, of Quincy, in the coimty of Norfolk and State of Massachusetts, have invented an Improved M achine for Burnishin g the Heels of Boots and Shoes; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this speciiication, is a description of my invention sufficient to enable those skilled in the art to practice it.

The invention relates to the specific organization and details of organization of a machine for burnishing the curved edges of the heels of boots and shoes. In such organization, I jack the shoe upon a pivoted arm or lever, to which a reciprocating rotative movement is imparted, the shoe being stationary with relation to said arm, and in the plane of the heel-edge I place a slide or frame, with which are connected a series of yielding burnishers, that clasp or bear against the heel-edge on three sides, or so that, by the reciprocating rotative movements of the shoe, the whole curved length of the heel-edge is brought to the action of the burnishing-faces. This slide has provision for movement toward and away from the heel, and for movement vertically, or in a plane to bring the burnishers against the whole width oflieel-edge. The invention consists in the organization thus generally described, and in details of construction and arrangement pertaining to such organization.

The drawing represents a machine embodying the invention.

Figure l shows the machine in side elevation. Fig. 2 is a front view thereof.

a denotes an upright, into the top of which enters a pivot-pin, I), projecting from an arm, c. Extending up from this arm in the line of the pivot b is a last-pin, d, upon which is placed the last that carries the boot or shoe to be heelburnished, the shoe being otherwise held in position by a suitable clam p-plate, c, and clampscrew f. The outer end of the arm c has jointed to itlinks h, that connect the arm with a slotted lever, z', pivoted at k, and having extending through it a crank-pin, l, projecting from va crank-wheel, m, on a shaft, n, rotation of this sha-ft imparting a reciprocating rotative movement to the arm c, and the boot or shoe jacked thereto. From the standard a eX- tends an arm, o, through which passes a bar, 1, that bears a horizontal plate, r, and upon this plate is mounted and slides a plate, s, that carries the burnishers, the plate s being in the plane of the heel-edge, and the yielding burnishers being arranged as seen in Fig. 3, which shows the burnisher-carrier in plan.

Three burnishers, t, t, and u, are shown, t t denoting side burnishers, acting against the opposite curved edges of the heel, and u being' a center burnisher, operating against the curved rear edge ofthe heel, and each being yielding, the side burnishers being at the ends of plate or bar springs c, and the center burnisher at theend of a rod, fw, thrown forward by a spring, av.

The carrier-plate s may be moved up to and back from the heel by a screw, y, and the bar q is made a gear-rack, to be moved up and down by a gear-lever, z, the vertical movement ofthe rack imparting such movement to the burnishers as will move their operating-faces across the whole width of heel-edge face, while by the reciprocating movements of the jack the whole length of curved heel-edge is subjected to the burnishing action of the burnisher-faces.

The burnishing-faees of the yielding burnishers t t u may be made of such length that they will cover the entire length of the curved surface of the heel, in which case a reciprocating vertical movement of the burnishers will sufice to burnish the whole curved surface of the heel without imparting reciprocating movement to the jack; or, instead of a series of burnishers, one burnisher-face may thus eX- tend around the whole length of curved edge'.

of heel, so that, by imparting a vertical reciprocating movement to the burnisher or to the jack, the whole heel-edge will be burnished.

I claim- 1. The combination of a series of burnishers connected with a normally stationary plate or holder, and pressed inward by suitable springs, with a rotativelyreciprocating jack, which brings the whole length of curved heel-edge under the action of the burnishing mechanism.

2. In combination with the sci-ics of yieldin g bnrnishers land reciprocatii1g` jack, the support-plate r, made vertically adjustable, substantially as described.

3. In combination with the sercs of yielding bnrnishers and reciprocating` jack, a carrier-plate, o, made adjustable horizontally, substantially as described.

4. In combination with a boot or shoe jacking mechanism, the burnishcr or bnrnishcrs upon a stock or carrier arranged to reciprocate in a right line in a direction across thc edges of the lifts, substantially as described.
